Safety of Difluoromethane Storage and Transportation Specification

Introduction

Difluoromethane is a common chemical production raw material, widely used in refrigeration, foaming, solvents and other fields. However, due to its flammable, explosive, toxic and other characteristics, it is necessary to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safety storage and transportation specifications of difluoromethane.

1. the physical and chemical properties of difluoromethane

Difluoromethane is a colorless, odorless, non-flammable gas with a chemical formula of CH2F2 and a molecular weight of 46.03. It has a destructive effect on the atmospheric ozone layer, so it is necessary to strictly control emissions during production and use.

2. the risk of difluoromethane

1. Flammable and explosive: After difluoromethane is mixed with air, it will burn or explode under certain conditions, so it is necessary to avoid use or storage under open flame or high temperature environment.
2. Toxicity: Difluoromethane is toxic to humans and animals. Prolonged exposure or inhalation of high concentrations of difluoromethane gas may cause poisoning, dizziness, nausea, vomiting and other symptoms.

3. difluoromethane safety storage specifications

1. The storage place should choose a dry, well-ventilated, and cool place, away from open flames, heat sources and direct sunlight.
2. The storage container shall comply with relevant national standards and have sufficient strength and sealing performance to prevent gas leakage.
3. The storage area shall be provided with obvious safety warning signs, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. Difluoromethane Safety Transportation Specifications

1. Transport vehicles should comply with relevant national standards and have sufficient strength and sealing performance to prevent gas leakage.
2. During transportation, it should be kept stable to avoid violent vibration, collision and dumping.
3. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment. Drivers and escorts shall be professionally trained to understand the nature and safe operation procedures of difluoromethane.
4. During transportation, the road traffic safety regulations shall be complied with, the speed shall be kept stable, and speeding and fatigue driving shall be avoided.
5. The goods shall be inspected regularly during transportation to ensure that the goods are in normal condition and free of leakage.

5. leakage emergency treatment

1. When difluoromethane leakage is found, the emergency plan should be started immediately and professionals should be organized to deal with it.
2. Cut off the leakage source and use special equipment to collect the leakage to prevent the leakage from spreading into the air.
3. Ventilate the leakage area to ensure air circulation.
4. If any person comes into contact with the leakage or has symptoms of poisoning, he should be sent to a doctor for treatment immediately.

conclusion

difluoromethane as a common chemical production raw material, in the process of storage and transportation need to strictly abide by the relevant safety regulations to ensure the safety of personnel and the environment. By understanding the physical and chemical properties and risk of difluoromethane, and mastering its safety storage and transportation specifications, accidents can be effectively prevented and the safety of production can be guaranteed.
